Ultraviolet Microscopy

  • K. Fukazawa
Part of the Springer Series in Wood Science book series (SSWOO)


Lignin in wood absorbs ultraviolet light much more strongly than the polysaccharide components. It is not surprising, therefore, that many authors have used UV microscopy to study lignin in wood. Lange (1954) determined the lignin content in the middle lamella and the secondary wall of spruce tracheids from UV photomicrographs. Wardrop (1957) utilized UV photomicrographs for detecting the beginning of lignification and its subsequent progress in differentiating xylem. Both Lange (1954) and Wergin (1965) elucidated the unusual lignin distribution in compression wood by means of UV photomicrographs. Jayme and Torgersen (1967) reported on the topochemistry of delignification in sulfite and sulfate pulping of spruce wood using a Leitz UV microscope.
